Hi,
this patch fixes PR64980 and PR61960 at the same time. The unreduced test case for PR64230 is also included, because a previous version of this patch caused this test to fail but the complete test suite passed without any indication of any problem. Boot-strapped and regression-tested on X86_64-unknown-linux-gnu. OK for trunk? Thanks, Bernd. PS: Special thanks to Dominique for his help with testing of this patch.
